If you are interested in the cohomology of a finite group, you can decompose that into primary components (one for each prime diving the order of the group). Taking coefficients in a field of characteristic p kills all components other than the p-primary one. In a similar way, you can localise/complete a space with respect to a prime and consider homotopy, homology or cohomology with coefficients in a field of a prime characteristic to either get p-local information about the space or trivial structures, depending on your characteristic. They have their use.

That is a good guess, but we must remember that 0 and 100 are the holy numbers God gave us as the freezing and boiling point of water. The correct answer is 24, as that is the length of the rebirth cycle of the Sun. For humans, it is also the threshold between the bright and dark age.
